      Abstract

      Rice is the main commodity for Indonesian people. However, the availability of rice in Indonesia is not in accordance with the increasing demand from the public. One attempt to solve the problem is by diversifying food staple so that community needs can be met. Instant imitation rice are examples of modified processing tubers that resemble rice with excess presentation time faster than ordinary rice. Purple sweet potato was chosen as raw material for the manufacture of imitation instant rice because it contains antioxidant compounds most complex. Purple sweet potato contains nutrients and a higher economic value than rice, if processed properly. The processes of making an instant rice from purple sweet potato are through the selection phase that no defect (reject), washing, steaming, peeling and cutting the skin, digestion with the addition of process water as much as 0.189 L / kg of the product, adding flour as much as 0,781 kg / kg products, with the addition of pasta ratio purple sweet potato and wheat flour 1: 1, then made size reduction by cutting, steaming for 25 minutes, and drying in an oven for 2.5 hours at a temperature of ± 60 ° to ± 10% moisture content. Products were packed in aluminum foil with a 250 gram package contents purple sweet potato which needs as much as 0.630 kg / kg of product. The test results showed that the rice mock proximate instant of sweet potato has a moisture content of 10.02% (bb), mineral 2.18% (bb), fat 2.15% (bb), protein 8.05% (bb), and carbohydrates 77.60% (bb). The receptivity of the products known by the organoleptic test by respondents to the taste, smell, aroma, texture. Organoleptic results show the percentage of choice like a row: the scent of 78.57%, 67.86% flavor, texture 60.72%, 57.15% and color. Based on economic analysis has been calculated, the manufacture of imitation instant rice can provide a profit of Rp. 458.193 / packaging (250 grams) on the scale of production of 50 kg of dry weight of product per 2 days (200 packs per production), with a payback period of over 0,455 years.
